What attaches to medial epicondyle?
The medial epicondyle gives attachment to the ulnar collateral ligament of elbow joint, to the pronator teres, and to a common tendon of origin (the common flexor tendon) of some of the flexor muscles of the forearm: the flexor carpi radialis, the flexor carpi ulnaris, the flexor digitorum superficialis, and the …
What muscles attach to the Epicondyles at the elbow?
Musculature
Muscle | Origin |
---|---|
M. pronator teres | caput humerale: septum intermusculare mediale of the epicondylus medialis humeri caput ulnare: medial edge of the tuberositas ulnae |
M. flexor carpi radialis | fascia antebrachii of the epicondylus medialis humeri |
M. palmaris longus | fascia antebrachii of the epicondylus medialis humeri |
Where does the UCL attach?
The ulnar collateral ligament complex is located on the inside of the elbow (pinky or medial side). It is attached on one side to the humerus (the bone of the upper arm) and on the other side to the ulna (a bone in the forearm).
What tendons are involved in medial epicondylitis?
The flexor carpi radialis and the pronator teres are the most commonly involved tendons in medial epicondylitis. [3] The medial epicondyle also serves at the origin of the ulnar (or medial) collateral ligament (UCL). The common flexor tendon and UCL provide stability to flexion and valgus forces at the elbow.
What does the medial epicondyle of the humerus articulate with?
It articulates with the radius and ulna bones of the forearm to form the elbow joint. Distally, the humerus becomes flattened. The prominent bony projection on the medial side is the medial epicondyle of the humerus.
What muscles attach to the lateral epicondyle of humerus?
Specifically, these extensor muscles include the anconeus muscle, the supinator, extensor carpi radialis brevis, extensor digitorum, extensor digiti minimi, and extensor carpi ulnaris.
Which muscles originate on the medial epicondyle of the humerus?
The medial epicondyle is the common origin of the forearm flexor and pronator muscles. The most common site of pathology is the interface between the pronator teres and the flexor carpi radialis origins.
Is the MCL and UCL the same?
Sometimes also referred to as the ulnar collateral ligament (UCL), the MCL of the elbow attaches the ulna (which, along with the radius, makes up the bones of the lower arm) to the humerus, the bone of the upper arm.
What muscles attach to the UCL?
This ligament is in relation with the triceps brachii and flexor carpi ulnaris and the ulnar nerve, and gives origin to part of the flexor digitorum superficialis.
What attaches to medial epicondyle of femur?
The medial epicondyle is more prominent and provides attachment for the medial (tibial) collateral ligament (MCL).
What causes medial epicondylitis?
Medial epicondylitis is caused by the excessive force used to bend the wrist toward the palm. This can happen when swinging a golf club or pitching a baseball. Other possible causes of medial epicondylitis include: Serving with great force in tennis or using a spin serve.
Is the medial epicondyle of the humerus vulnerable?
Medial epicondyle of the humerus. The medial epicondyle protects the ulnar nerve. The ulnar nerve is vulnerable because it passes close to the surface along the back of the bone. Striking the medial epicondyle causes a tingling sensation in the ulnar nerve. This response is known as striking the “funny bone”.
What does it mean to have medial epicondylitis?
Medial epicondylitis, also known as “golfer’s elbow” or “thrower’s elbow”, refers to the chronic tendinosis of the flexor-pronator musculature insertion on the medial epicondyle of the humerus as a result of overuse or repetitive stress.
Where are the attachment points of the humerus?
Lateral Epicondyle is a rounded protuberance at the distolateral terminus of the humerus. The posterior surface of the lateral epicondyle accommodates as an attachment point for some of the muscles that extend the wrist and fingers of this hand.
Is the medial epicondyle inferior to the supracondylar ridge?
Additionally, the medial epicondyle is inferior to the medial supracondylar ridge. It is also proximal to the olecranon fossa . The medial epicondyle protects the ulnar nerve, which runs in a groove on the back of this epicondyle.
